I have not used MorphOS on my G5 PowerMac until just recently, as I was waiting for the support of R400 based video cards, which came some time ago, but I delayed installing to the G5 even longer due to moving to a different house and having most of my hobby computer gear packed up.

With the event of last weekends Amiga30 computer show in Mountain View, California, I could delay no longer, as I needed the G5 system for the show, so I finally completed the installation of MorphOS3.9 on my G5 tower and used it to display during the show on the dedicated MorphOS table. The install took me several tries and a couple of days, but I was finally successful in getting it installed and working, but the system ability to boot into MorphOS3.9 is very unreliable. It seems to run fine once it boots up, and I have seen it run for many hours without any problems, but often it will refuse to fully boot up. It sometimes gets stuck on an all white screen, or the MorphOS3.9 splash screen, while other times it will get further and freeze on the Ambient screen before it has drawn any of the device icons. Would it be helpful to anyone if I attempted to diagnose the freezing up during the boot process by recording some debug output for others to look at? I don't know how to do that, as the results would be over my head, but I will find out how to get the debug output, if anyone wants it. I just figured since the point at where the system is freezing up during the boot process is different almost each time, the results may not be as helpful as they would be if it were freezing at the same exact point each time.

Since I am using a PC video card which has been re-flashed with a Mac ROM to work in my G5, I won't complain, or assume that it is a problem with the OS, as re-flashed video cards are not officially supported by the MorphOS Dev. Team. Instead, I will look around for a genuine Mac video card that has the same or better performance as my FireGLX3 Radeon w/R420 GPU, and see if that solves my intermittent booting problems. If the intermittent booting problems still exist after switching to a genuine Mac video card, then I must have a corrupted installation, a hardware fault somewhere else in the computer, or there is some kind of bug in MorphOS3.9 that only shows up on G5 systems.
